Bluetooth® monitoring app

This battery give you the capability to easily monitor its key data wirelessly, via Bluetooth® connection. You can access this feature by downloading the Hardkorr Battery app which is available for iOS® and Android® devices. With the app you can view:

KEY INFORMATION
State of charge, current voltage, available capacity, status, health.

DETAILED INFORMATION
Current voltage, net current in/out, status, cycle life, temperature.

CELL STATUS
Current voltage of each cell to ensure they are balanced.

CONTACT DETAILS
Our website, address and email in case you have a question or problem.
The app also records a log of any instances where a BMS protection circuit is activated, including over-charge, over-discharge, under-voltage, over-current and over-temperature. You can find it by pressing the shield icon in the top-right corner of any screen.

Handy remote reset switch

The Battery Management System (BMS) inside all lithium batteries contains a protection circuit which trips if the voltage drops below a certain setpoint. In the case of Hardkorr batteries, it is set at 10.0V. This circuit prevents damage to the battery by putting it into a ‘sleep’ mode until it is reset.

In the past, resetting the battery after the over-discharge protection was activated was not easy. Whilst some battery chargers do contain a “wake-up” function, most people had to resort to applying a constant voltage above 12V across the terminals using jumper leads or home-made wires. This was fraught with danger; damage to appliances or the battery were not uncommon.

Our batteries provide an easy solution to this problem; simply connect our included remote reset switch to the socket on the top face of the battery and hold down the button for 5 seconds, and the over-discharge circuit will reset itself. The button can also be flush-mounted into your 12v setup if desired.

Oversized Terminals

Direct +/- connection to the battery. The oversized terminals not only simplify installation but also enhance the overall reliability of your power source, providing peace of mind during off-grid adventures.

Antenna port

As the battery is encased in aluminum, we positioned the Bluetooth antenna externally to ensure an extended range when utilizing your Bluetooth app for monitoring the battery status.

With a narrow 50mm profile, 250Ah continuous discharge rate (perfect for running your favourite 240V appliances up to 2500W from an inverter), and Bluetooth® monitoring, these batteries are perfect for those after a reliable, full-featured battery, ready for touring.

Ask any full-time tourer to tell you about some of the biggest challenges while travelling the country and you’ll likely find their answer has something to do with 12V power and space. Our 210Ah Slimline Lithium Batteries look to solve both these problems.

Built into a narrow 50mm heavy-duty aluminium case, the batteries are ideally suited to being mounted behind the rear seats in a 4×4 cab, or up on the wall of a canopy, allowing you plenty of extra space to pack the rest of your gear. The batteries can be mounted in any orientation and come with eight brackets, giving you plenty of flexibility in how you decide to mount the unit.

Engineered using high-quality aluminium-encased prismatic cells, our 210Ah battery weighs just 25kg and has excellent vibration resistance qualities making it ideal for those looking to set out on a cross-country trip. The battery has a full 210Ah of usable power – ideal for running 12V fridges, lighting, and pumps – but also has the capacity to run even larger items.

Equipped with an advanced internal Battery Management System (BMS), the battery is capable of discharging at 250A continuous which means that it’s able to run up to 2500W from an inverter. This enables the battery to run, through an inverter, your favourite 240V appliances like coffee machines, toasters, and induction cooktops, without skipping a beat – a feat that hasn’t previously been possible with batteries at this size. Additionally, the BMS allows the batteries to be able to be either linked in parallel or series with up to four other batteries to create larger battery banks of up to 840Ah or systems at up to 48V.

The batteries are certified in accordance with some of the country’s most stringent safety and performance standards, have been fully tested and certified by an internationally renowned lab, and are backed by a comprehensive 5-year warranty.

ATTENTION: This battery is not suitable for under bonnet use.

* Note on discharge current: if you connect multiple batteries in parallel, the maximum discharge current is multiplied by the number of batteries in the array. For example, if you connect two of these batteries in parallel you can discharge at up to 400A.

Prismatic and cylindrical cells both have inherent advantages and disadvantages. Batteries which use prismatic cells are somewhat lighter than those with cylindrical cells, and are easier to manufacture due to having fewer connections between cells. Cylindrical cells, on the other hand, are usually more efficient in their energy usage, produce somewhat less heat and tend to be more reliable than their prismatic counterparts.

The improved cell reliability and efficiency of cylindrical cells are what made us decide, like Tesla and Rivian, to manufacture these batteries from cylindrical cells.
